IMPROVEMENT IN TOOL-HANDLES.

Specification forming part of Letters Patent No. 123,652, dated February13, 1872.

To all whom it may concern:

Be it known that I, ALFRED WEED, of Boston, in the county of Sufiolk andState of Massachusetts, have invented an Improved Tool- Glamping Handle;and I do hereby declare that the following, taken in connection with thedrawing which accompanies and forms part of this specification, is adescription of my invention suflicient to enable those skilled in theart to practice it.

United States Letters Patent No. 68,584 were granted to me for animproved file, which file was made without a tang, but with provisionfor enabling it to be grasped firmly and immovably between twoclampingjaws at the end of a suitable handle; Letters Patent No. 68,585having also been granted to me for such a handle.

My present invention relates to an improvement upon such file ortool-holding handles.

In the patented handle referred to, the movable jaw was fed toward theother jaw, and

clamped upon the file shank held between them by a nut and screw. Saidnut and screw are objectionable, as they project out into a positionWhere they form an obstruction to the free handling and manipulation ofthe tool.

In my present invention I make the movable jaw as a hinged leverplate,one end of which is forced down upon the fileor other tool shank byforcing the other. end outward, said forcing outward being accomplishedby making the handle with a screw-threaded end, working into anut-thread on a sleeve or ferrule, which forms the head of thestationary jaw, and with an expanding cone, the forward movement ofwhich forces the adjacent end of the clamp-lever outward, and the innerend against the file-shank. It isin this improved clamping-handlethat'my present invention The drawing represents in front view, in

sectional elevation, and in end view a handle embodying theimprovements.

at denotes the end of a file clamped to the handle. bdenotes the handle;0, the screwthread around the inner end of the handle; 01, the expandingcone at the end of the handle. e is the stationary jaw of the clamp,said jaw being made with the nut-threaded ring, ferrule, or sleeve fforming its head. 9 denotes the movable jaw, hinged to the jaw e, asseen at h, and having aninwardly projecting end, i, against which thecone (1 acts to force it outward when the handle is rotated, and therebydriven endwise into the ring f. The jaw g has an angular tongue ortenon, k, which fits into a corresponding recess, Z, in the shank of thefile to be held.

For grasping three-cornered files, an angular notch, m, running in theopposite direction, may be made in the stationary jaw e. The handle I)being turned back, the file-shank is introduced between the jaws and thetongue 70 into the notch l, and the handle is then moved forward, thecone pressing upon the inner end of the movable jaw, and pressing downthe opposite end against the file, and clamping it tightly between thetwo jaws.

I claim- The combination of the stationary jaw e, having a nut-threadedring, f, with the movable jaw g, pivoted to the stationary jaw, andoperated by the cone d on the end of the screw-threaded handle b,substantially as described. p
